to a handle.

The various features of novelty should be apparent from a reading of the following specificationand relate to the durability and adaptability of .the device in general.

In the accompanying drawing I have illustrated one embodiment of the design of my improved holder.

Fig. 1 shows a front view of the mop holder with the handle attached and a part of the front plate cut away to show the detailed construction.

Fig. 2 is a View taken from the with the handle removed.

ness of parts.

Referring to the drawing I will now describe in detail the construction and operation of my device.

The holder comprises a metallic part consisting as shown of two metal plates I and 2 riveted or secured together in any desired manner. The plates are formed before assembly so that when secured together they form opening 3, for receiving the handle,

a cup shaped in the center and a pair of holes or channels 4 and 5 for receiving the prongs 6 and 'I.

Communicating with the cup shaped opening 3 is another hole 8 for receiving the prong 9.

The mop clamp having the three prongs 6, I and 9 is of metal rod, bent as shown, and having its center prong 9 threaded for a considerable distance throughout its length. The prong 9 is much longer than prongs 6 and 'I and extends loosely through hole 8 and into the center of hole or cup 3. The Wood handle I 0 has a metallic end or cap II riveted thereto by rivet I2. This cap II has a shoulder I3 running around the outside and engaging the upper side of parts I and 2 before the end of member I I engages the bottom of cup 3. There is a threaded hole extending up into the handle and through cap I I, having threads to fit the threaded end of prong 9. out at I 4 as shown clearly in Fig. 3.

The outer ends of parts I and 2 are out These openings in parts I and 2 register so as to form a pocket into which the bumpers I5 and I6 are placed before the clamp is inserted. The construction of bumpers I5 and I8 is clearly shown in Fig. 4; They comprise a rubber cylinder or barrel shaped 5 part having slots cut therein at IT and I8, leaving a center part I9 as a complete circular ban-d. The bumpers are thicker in the center as shown and the part I9 is inserted into the openings such as shown at it. and I8 are stretched and slipped over the bulge of parts i and 2 as shown in Figs. 1 and 2 so that the prongs l3 and l pass through the openings in parts I9 of the bumper and lock them in place.

Referring now to Fig. 1. The bumpers I5 and 15 is are first inserted in slots I4 as shown. The mop fabric, which may be of any desiredform and which is indicated at 20, is now folded over the rod 2I of the clamp and prong 9 is forced through the center thereof. The prongs 6, I and20- 9 of the clamp are then inserted into the metal body, the prongs 6 and I passing into the outer holes with which they register and holding bumpers i5 and I6 in place, while prong 9 extends up into cup 3. The handle is now inserted into cup 3 and threaded over prong 9. By turning the handle I0 the prong 9 is drawn up into the cup 3 until horizontal rod 2I of the clamp has securely clamped the mop fabric against the lower edges of parts I and 2, in which position shoulder I3 is forced against the upper rim of cup 3. A slot 22 is provided in the upper part of plate I for locking the handle to the cup after it has been screwed down as far as possible. A plurality of such slots may of course be provided if desired. A hole is provided through shoulder I3 and a cotter pin 23 or any manner of pin is inserted through this hole and into slot 22 as shown into slot 22 to lock the handle and prevent its loosenmg.

It will be seen that the mop holder described is compact and rigid. The clamp 2| is a rigid rod which securely clamps the mop fabric and holds the bumpers in place. The bumpers are removable and may be readily replaced and the whole is so constructed as to out-wear most devices of its kind now known. There are no springs or clamps to wear out and continued use cannot change its ability to securely clamp a fabri'c in place.

Having fully described the details and operation of the device, what I consider to be new and desire to have protected by Letters Patent will be pointed out in the appended claims.

The flaps adjacent the slots I1 10g What I claim is:

1. A mop holder comprising a mop head and a handle cooperating therewith, said mop head consisting of two metal plates having parallel grooves formed therein, said plates secured together with the grooves registering to form three channels through the head parallel to the flat plates, 2. three pronged clamp having the center prong threaded, the prongs of the clamp inserted into one end of the parallel channels and freely movable endwise therein, the threaded prong extending into the center channel, the grooves forming the center opening being larger at the edge of the plates opposite the clamp to form an enlargement in the center channel, a threaded opening in the end of said handle, said end of the handle inserted in the enlarged end of the center channel to engage the threaded tine and draw the clamp against the head when the handle is rotated.

2. In a mop holder, a mop head comprising a flat metal plate, a series of holes passing through the flat plate parallel to the plane thereof, a mop clamping member having a bar and a plurality of tines all rigidly secured to the bar at one end, one of said tines threaded on its end and opposite the bar, the tines of said clamping member registering with and inserted into one end of the holes through the plate with the threaded tine passing into the center one of the holes, said center hole having an enlarged opening on the end opposite that in which the threaded tine is inserted, a handle having a threaded hole in one end, said one end of the handle inserted in the enlarged opening in the center hole to meet the threaded end of the center tine, the threads in the handle engaging the threaded end of the center tine to draw the clamp bar against the head when the handle is rotated in the enlarged opening.

3. In a mop holder, a handle, a mop head consisting of a flat plate having a plurality of openings therethrough in the plane of the plate, one of said openings expanding at one side of the plate into a cup shaped opening, a mop clamp 5 having a threaded shaft and a plurality of prongs, the shaft and prongs inserted into the openings at the side of the plate opposite the cup shaped opening with the threaded shaft extending into said cup shaped opening, said handle having one end inserted in said cup shaped opening, said end having a threaded hole therein cooperating with the threads on said shaft to draw the clamp against the head when the handle is rotated, and

a pair of bumpers each having a portion extending into one of said openings, each portion engaged by the prong inserted in the respective opening to hold the bumper in place to protect the edges of the plate.

4. In a mop holder, a mop head comprising a flat plate having a plurality of openings extending from one side of the plate to the opposite side in the plane of the plate, one of said openings expanded into a cup shaped opening at the other side of the plate, and two of said openings running close to the remaining two sides of the plate, a slot extending from each of said last two sides into the said last two openings, a pair of rubber bumpers each having a portion extending into one of said slots and into the opening connecting therewith, a mop clamp having three prongs, one extending through one opening into the cup shaped opening and the other two extending into the other openings and engaging the portions of said bumpers to hold them in place, one end of said handle inserted into said cup shaped opening and cooperating with the prong extending thereinto to tighten the clamp against the head.
